［摘要］针对水平荷载作用下现浇混凝土空心板柱结构等代框架计算模型中等代梁宽度的取值问题，运用有限元分析程序对不同几何尺寸的空心板柱结构进行水平荷载作用下的弹性计算分析，研究等代梁宽度与结构几何参数的内在关系，从而得到等代梁宽度的计算公式，为进一步计算提供依据。

Abstract:In order to study the equivalent frame calculation modes for reinforced concrete hollow slab-column structures under lateral load in the elastic analysis, the models of reinforced concrete hollow slab-column structures with different dimensions were established using finite element program. The internal relationship between the effective beam width and the frame dimensions was studied.The formula for calculating the effective beam width was obtained.

Keywords:hollow slab-column structure; lateral load; equivalent frame; effective beam width; frame dimensions
